An anti-tamper tag arrangement includes a release liner and a thin film strip having first and second sides and a longitudinal direction.

A coating of pressure-sensitive adhesive is deposited on the second side of the thin film strip. The thin film strip is removably fixed to the release liner by the adhesive coating.
